Like a hole in the head

nail The construction worker in Los Angeles who had an accident with a nail gun last month is expected to fully recover. From the Associated Press:

"(Isidro) Mejia, 39, was atop an unfinished home when he fell from the roof onto a co-worker who was using the nail gun, Los Angeles County sheriff's Deputy Mark Newlands said.

The two men tried to grab each other to keep from falling, but both tumbled to the ground. At some point, the nail gun discharged and drove the nails into Mejia's head.

'They're extremely powerful," Newlands said. "They've got to drive through three-quarter-inch plywood.'"

The surgeons removed six nails, three of which had penetrated Mejia's brain. Link
